Louis Erard x Alain Silberstein Le Diptyque

The Louis Erard x Alain Silberstein Le Diptyque is a rare two-watch collector’s set, limited to just 28 pieces, bringing together two distinct interpretations of Silberstein’s playful design language. The set comprises Le Régulateur Blanc and La Semaine Blanche, both housed in 40mm cases combining microblasted grade 2 titanium with polished grade 5 titanium, sapphire crystals and exhibition case backs.

Le Régulateur Blanc uses the automatic Sellita SW266-1 calibre and presents time through a regulator-style display, separating hours, minutes and seconds with Alain Silberstein’s signature red, blue and yellow hands. La Semaine Blanche is powered by the automatic Sellita SW220-1 calibre and adds Silberstein’s expressive weekly calendar, replacing traditional day indications with his recognisable “Smiley”mood display, alongside hours, minutes, seconds and date.

Both watches offer approximately 38 hours of power reserve and 100 metres of water resistance, making the set technically practical while remaining highly expressive. The opaline matt silver dials, colourful geometric hands and playful detailing create a distinctive balance between Swiss mechanical watchmaking and modern artistic design.

This pre-owned piece is new and unworn, and comes as a full set with its original box, papers and warranty dated May 2022. It will also be accompanied by an additional one-year TLE warranty for added peace of mind.
